Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a2afc59fb25027749bd41c44f47382522232019e

----------------------------------------------------------------------

Patch series "vmalloc() vs bulk allocator", v2.

This patch (of 3):

Add a "node" variant of the alloc_pages_bulk_array() function.  The helper
guarantees that a __alloc_pages_bulk() is invoked with a valid NUMA node
ID.
